Hello,
I've got a bunch of questions regarding Intel Rapid-Start-Technology. I'll try to explain my problems step by step.
My girlfriend bought a Samsung NP540U3C Ultrabook. I replaced the HDD with a 120 GB Samsung 840 Evo SSD and reinstalled Windows 8. The Ultrabook has a second SSD (24 GB mSATA) built-in. The 24 GB SSD used to have two partitions. A 3 GB partition and a 19 GB partition. The 19 GB partition has been used for Express Cache (mSATA SSD buffering I/O of HDD). Since I built in the the 120 GB 840 Evo the Express Cache partition hasn't been needed any longer, so I've had it deleted. The 3 GB partition was used for Intel Rapid Start I think. Which made me wonder because I thought the Rapid Start partition has to be at least a size equeals to the size of RAM installed. Anyways, I deleted that partition, too. So the 24 GB mSATA SSD had been completely empty. I created a new GPT partiton, used all 24 GB straight through. I wanted to create a partition for Intel Rapid Start again. Maybe I'll upgrade the RAM to 12 GB, so I'll be fine with the size of the partition.
When attempting to set the ID of the GPT partition as described in the online manuals "set id=84 override" I've got the error message "The specified type is not in the correct format".
1.) So I used Google search, found a lot of people are telling that the error is because of the GPT partition. Is that correct?
I'll then tried to use the command "set id=D3BFE2DE-3DAF-11DF-BA40-E3A556D89593" which at least didn't give me any errors. I could install Intel Rapid Start Technology service and I can access it from the system tray (Windows 8 64 Bit) and set the timer.
2.) But the Windows partition manager doesn't tell me it is a "hibernation partition". Maybe that is because of the GPT partition, too?
I don't know whether Intel Rapid Start is working correctly or not.
3.) Are there any command line tools to verify a working status?
When closing the notebook (susped) it goes off, then turns on again and then after a few seconds turns completely off again (Intel Rapid Start timer set to 0).
4.) From my understandig that is the way it is supposed to work, but I don't know whether Intel Rapid Start is really working or not. I think the notebook goes into S3 (suspend to RAM) when closing it and then turns on again to go into a advanced suspend (S4?) to write the content of the RAM to the Rapid Start partition.
What is the point of that anyways? Isn't that similar to hibernation state? Couldn't one just create a drive on the second SSD (mSATA 24 GB) and force Windows to write the hibernation file to that drive? What's the point of using Intel Rapid Start instead? Besides the fact that the user isn't seeing the partition and can not missuse that partition I don't see any advantages of Intel Rapid Start Technology.
Thanks for any help on this.
